Setting Write-Protect Mode for the PCDLocate this document in the navigation structure

Use

You can prevent data from being written to the PCD by activating write-protect mode. For example, during data migration from a source system to another system, you can activate write-protect mode on the source system to prevent data from being written to it during the migration process.

You set write-protect mode in SAP NetWeaver Administrator. More information: SAP NetWeaver Administrator .

The following components are affected by write-protect mode:

Component

Effect

Portal

Object editors are either not available at all or only have limited functionality. For example, portal administrators cannot import or export packages using the Package Transport Editor. It is also not possible to create new objects, delete objects, or edit objects using the object editors. Personalization of the portal themes is not available. When the portal is in write-protect mode, error messages appear when you attempt to call functions that are currently not available.

Collaboration

You cannot create new rooms, or edit or delete existing rooms.

User Management Engine

You cannot create portal roles, but you can create and change UME roles because they are not stored in the PCD. You cannot assign portal roles to actions, neither in the user management administration console nor in the Role Editor.
Procedure

You activate write-protect mode for the PCD in SAP NetWeaver Administrator using the following properties:

  1. Pcd.Pl.WriteProtectActivated

    A Boolean property that defines whether write-protect mode is activated. By default it is set to false .

    To activate write-protect mode, set the value to true .

  2. Pcd.Pl.WriteProtectCause

    Specifies why write-protect mode was activated. This information appears in log files.

Note

It is not necessary to switch on write-protect mode to create an online backup. For more information about online backup, see SAP note 779708.

Note

Write-protect mode can only be configured for the entire cluster, and the properties are propagated to all the cluster instances.
